    Why the Tacoma Narrows Bridge Collapsed

    Why the Tacoma Narrows Bridge Collapsed

    Wind can be one of the most critical and complicated loads on civil structures. The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure. When you push the envelope, you have to be vigilant because things that didn’t matter before start to become important (e.g. wind loads on lighter structures). Unanticipated challenges are a cost of innovation and that’s something that we can all keep in mind.

    Why Tunnels Don't Collapse

    Why Tunnels Don't Collapse

    This video shows how simple reinforcement is used to prevent collapse of rock tunnels. Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

    Why Concrete Needs Reinforcement

    Why Concrete Needs Reinforcement

    This video shows more destructive testing to answer your questions about concrete. Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement.

    What is Prestressed Concrete?

    What is Prestressed Concrete?

    Sometimes conventional reinforcement isn't enough. The basics of prestressed concrete. Prestressing reinforcement doesn't necessarily make concrete stronger. But, it does increase the serviceability of concrete members by reducing the amount of deflection under load. This video explains the two most common types of prestressed concrete: pre-tensioned and post-tensioned. Prestressed concrete is used in all kinds of structures from bridges to buildings to silos and tanks. It’s a great way to minimize cracking and take fuller advantage of the incredible strength of reinforced concrete.

    Using Six Sigma DMAIC Methodology and Discrete Event Simulation to Reduce Patient Discharge Time in King Hussein Cancer Center

    Using Six Sigma DMAIC Methodology and Discrete Event Simulation to Reduce Patient Discharge Time in King Hussein Cancer Center

    Short discharge time from hospitals increases both bed availability and patients and families satisfaction. In this study, the Six Sigma process improvement methodology was applied to reduce patients discharge time in a cancer treatment hospital. Data on the duration of all activities, from the physician signing the discharge form to the patient leaving the treatment room, were collected through patient shadowing. These data were analyzed using detailed process maps and cause-and-effect diagrams. Fragmented and unstandardized processes and procedures and a lack of communication among the stakeholders were among the leading causes of long discharge times. Categorizing patients by their needs enabled better design of the discharge processes. Discrete event simulation was utilized as a decision support tool to test the effect of the improvements under different scenarios. Simplified and standardized processes, improved communications, and system-wide management are among the proposed improvements, which reduced patient discharge time by 54 from 216 minutes. Cultivating the necessary ownership through stakeholder analysis is an essential ingredient of sustainable improvement efforts.

    Sustainable Urban Freight Transport: a Global Perspective

    Sustainable Urban Freight Transport: a Global Perspective

    Life in the city relies on the smooth operation of urban logistics. Everything from retail to services, construction to waste collection rely on an efficient and reliable freight transport system. However, with the increasing pressures of urbanization, this has to be balanced with the environmental and social impacts caused by transport activity. This is the challenge of City Logistics, a field of study that has significant practical implications for the world and the cities we live in. It is not merely a question of what is involved, but what can be done about urban freight transport to improve it for the sake of economic efficiency, quality of life, and sustainability. From a systematic scientific foundation of the field, this course will take you on a journey to learn how city logistics is understood and practiced in cities around the world. Our instructors, members of a renowned global expert network, will teach you the basics of this highly complex social system. Using their experience in real-world projects, they will illustrate how the knowledge learnt in this course is applied across industry and the public sector. This course caters primarily to university students or professionals working in urban transport infrastructure planning or logistics management. Whether you are simply curious about the topic or you intend to develop a career in these fields, this course will give you the tools you need to understand the complexities of urban freight transport systems. The course emphasizes the theoretical foundation, the rigorous evaluation, and a multi-disciplinary approach to this complex area. Course participants will benefit from numerous case studies of best practice in selected cities around the world, in a variety of business settings. Our emphasis on the global perspective is particularly relevant, since an understanding of local culture and political climate is an important factor in the success of any city logistics intervention. The course will provide an avenue for students to learn from their peers about the challenges faced in their respective cities, and how to apply the principles learned to the challenges faced in their own cities.

    Solid State Physics

    Solid State Physics

    This course is intended for students enrolling for BSc with Education and BEd degrees. Solid state physics forms the backborn of physics. The module has four units: Introduction to solid state physics; Crystal defects and mechanical properties ; Thermal and electrical properties; and Band theory & Optical properties.In the first unit/activity i.e. introduction to solid state physics. The student is expected to explain the atomic structure, describe the various atomic bonds such as ionic bonds and covalent bonds. The learning will also require students to distinguish between crystalline and amorphous solids; polycrystalline and amorphous solids and to explain the production and use of X-ray diffraction. In the second unit i.e. crystal defects and mechanical properties, the learning includes, differentiating between the different types of crystal defects: the point defects (vacancy, interstitials, and substitutional) and dislocations (screw and edge). Here, the student learns that point defects are very localised and are of atomic size, while dislocation is a disorder which extend beyond the volume of one or two atoms. The effects of the defects on mechanical, and electrical properties of these defects are also part of the learning that will take place. In unit three the learning outcomes include definitions of heat capacity, and explanations of variation of heat capacity with temperature based on the classical, Einstein and Debye models. The students will be required to use the free electron theory to explain high thermal and electrical conductivities of metals and also be able to derive and apply the Wiedermann-Frantz law. Finally, in activity four, the expected learning should enable the students to use the band theory to explain the differences between conductors, semiconductors and insulators; explain the differences between intrinsic and extrinsic semiconductors in relation to the role of doping. At the end of it all, the students use the concepts of the interaction of electromagnetic waves (light) with materials to explain optical absorption, reflectivity and transmissivity.
